Date         Instr.  Description 
============ ======= ======================
2023-05-25   SES     Every second WOFFSET_ in bias files wrong since 21st Jan 2023. Changed in fits files on stella-ext.
2023-05-23   SES     A handful of flats and a single calib has wrong XORGIN_. Marked as failures=65535
============ ======= ======================
.. _WOFFSET: 
Due to unknown reasons, every second bias file has a wrong WOFFSET in its main header. Instead of \[819,0\] it read \[819,2336\]. This may be linked to another behaviour seen around the same date, which rendered every second image as a blank.

.. _XORIGIN: 
Affects flat20230208B-0262, flat20230208B-0316, flat20230214B-0018, flat20230309B-0044, flat20230324B-0237,

On reopening of the camera just prior to recording of these images, either setting of the window or setting of the binning was not answered with OK, though the read-out window and binning are obviously correctly set (also the immediate query after the set operation returned a correct size).
